how to build a regex to match a string with only an EVEN number of backslashes before it (or NO backslashes)? for instance, the string I want to match is a dollar sign followed by 1 or more digits.
 
to just match such a string, this would do: /\$\d+/
 
the backslash problem is throwing me, however, because I'd like to allow the end user to purposely escape said string with a backslash to avoid a match(\$1)...OR, if they need to include an actual backslash character before it, they'd need to *escape* the backlash while the string is still matched (\\$1)
 
# Some examples of what should and shouldnt match

# should match '$1'
"for the $1th time"

# should not match
"SELECT * FROM Product WHERE Price LIKE '\$2.59'"

# should match '$10'
"using fore- and back-slashes for emphasis: \\$10/"

# should not match
"escaping: \\\$6"

i'd much appreciate the help of monks wiser than myself!
